9 Claims.

This invention relates to boxes for honey, butter, lard, and similar semi-solid or viscous material, and particularly to a lining therefor. My object is to devise a packing box provided with a lining which will" be suitable for shipping such materials in comparatively large quantities, and which may be made of wood and lined with cardboard or similar material instead of being made of metal, thus saving metal, and reducing the weight and cost of the container.

The constructions are hereinafter more fully described and are illustrated, by way of example, in the accompanying drawing in which Figure 1 is a plan of a blank as scored and cut to form the lining;

Figure 2 a perspective detail showing the lining folded for insertion in a box;

Figure 3 a plan view of a corner of a box having the lining therein; and

Figure 4 a cross section of the box, lining and cover.

l is a lining blank of cardboard or other suitable material which is coated with moistureproof material such as parailin. 'I'he blank is cut and scored to form the bottom 2, sides 3, corner pieces 4, each comprising two corner sections 4a, 4b, and a 'ap 5 on each sid 3. Each corner piece is scored diagonally at 5 from the junction 1 of adjacent sides 3 to form the corner sections 4B, 4b. The naps 5 on the sides 3 are greater in length than the sides to which they are attached. Preferably both ends 5a and 5b of each flap 5 extend beyond both edges of the side 3 to which the flap is attached. A flap 8 is formed on one corner section 4a of each corner piece 4. The flaps 8 ,are of less length than the corner sections 4 to permit the adjacent flaps 5 to extend beyond the edges of their sides.

As the sides 3 are folded upwardly to set up the lining I into its box-like shape, the corner pieces 4 project outwardly and fold along the diagonal scorelinesli so that the corner sections 4a with the flaps 8 overlie the corner sections 4b- The naps 8 are then folded over the sections 4b to contact the outer surfaces of the sides 3 and thus close the upper edges of the sections.

During the folding in of the flaps 8, the ends 5B and 5b of the flaps 5 on the adjacent sides are moved into position one overlapping the other.` The flaps 5 are scored longitudinally to form inner flaps 5 and outer flaps 5d. The inner flaps 5 extend outwardly from their sides 3 to overlie the upper surface of the rim 9B of the box 9. It will be noted that the ends 5n of the aps v5 cover the upper surface of the box rim 9a at the corners thereof. Thus the inner surfaces of the box and the upper surfaces of the rim 9a thereof are completely covered by the one-piece 1ining l.

The ends 5ll of the aps extend beyond the sides 3 atdistance about equal to the width of the inner flaps 5. The ends 5b, which are adjacent the flaps 8 extend only a very short distance and are cut back on an angle, the end of the adjacent iiap 8 being cut with a. corresponding angle, so that when the flaps `8 are folded. and the box set up the inner edge ofthe flap 8 will t snugly into the corner between the adjacent side 3 and the corner section 4b. When the lining is set up the ends will overlap suiiiciently to form a tight joint.

After the lining in the box is filled with the material to be transported therein, a ilat cover I0, of moisture proof material such as paraffin coated cardboard, is. positioned on the inner flaps 5b. The outer flaps 5 are then folded inwardly to overlie and thus seal the marginal edges of the cover I0. A top Il is placed over the box and is nailed to the upper edges of the sides of the box by nails which pass through the cover I0 and flaps 5. The ends 58 of the outer flaps 5" on adjacent sides 3 overlie one another, and also the ends 5 of the inner flaps 5b, whereby the corners of the cover I0 are sealed suiliciently to prevent material, such as honey, butter etc. having a high viscosity, from running out even if the box be turned upside down or on a side.

, The score lines between the flaps 5 and lid run ata slight angle outwardly from the end of the flap 5 adjacent the flap 8. When the lining is set up in the box, the folded corner sections lie between the sides of the lining and the box for part only of the distance from one corner of the box to the other. between the side and the box the side of the lining is slightly bent and pushed up into contact with the side of the box. At this point the. inner aps 5u are of slightly less width than where the corner section is interposed. Thus the width of the inner aps is varied to compensate for the diierence in thickness of the sides so that when the lining is set up in the box the scored line between the outer and inner flaps, where the fold occurs runs substantially parallel to the Vouter edge of the top of the box.

What I claim as my invention i's: l. lA box lining blank formed of a single piece of cardboard or similar material scored to form a bottom, sides, corner pieces between adjacent sides, each corner piece being scored diagonally from the junction of adjacent sides to form corner sections, a nap on the outer edge of each side adapted to be bent outwardly substantially at right angles to each side, the flaps on the sides `'being of greater` length than the'sides to which at each corner when the lining is set up, andaps attached to the outer edgesof the corner sections of less length-than the corner sections Where the folded corner is not to permit the iaps onv the sideslto Aextend beyond the sides at the ends thereof adjacent the ilaps on the corner section.

' 2. A box lining blank formed of a single piece of cardboard or similar material scored to form V a. bottom, sides, corner pieces between adjacent that they extend beyond both edges of the sides whereby the ends of the aps will overlap at each corner when the lining is set up, and the flaps attached to the corner sections being of less length than the said corner sections to permit the aps on the sides to extend beyond both edges of the sides.
